As well as being the most decorated world champion in wrestling history, Ric Flair is renowned as one of the industry's greatest-ever talents thanks to a massively successful 40-year career. Officially a 16-time world champion, "The Nature Boy" actually considers himself to have won an unprecedented 21 world titles.
One of the biggest draws of the 1980s, Flair captured the NWA World Heavyweight Championship a record 11 times between 1981 and 1993. Although his second title win isn't officially recognized by the company and a further two were only retroactively acknowledged in 1993, "The Nature Boy" nonetheless accumulated over 3,000 days as NWA World Champion. Five of these reigns lasted over a year, with the longest an impressive 793 day stint between May 1984 and July 1986.
A short run with the WWF between August 1991 and February 1993 saw "The Nature Boy" capture the WWF Championship twice, although both reigns only combined for a disappointing 118 days before he departed the company.
After WCW split from the NWA in September 1993 while he was still champion, Flair enjoyed two reigns with the short-lived International Heavyweight Championship, which eventually became unified with the WCW World Championship in June 1994. However, these are no longer acknowledged as official world title reigns.
"The Dirtiest Player in the Game" captured his final world championship when he lifted the WCW World Championship for a record seventh time on May 29, 2000 after the belt had changed hands three times in a week. (It could be argued that Flair won eight world titles with the company, but his third reign isn't officially acknowledged after a double pin finish in a match with Ricky Steamboat in April 1994.)
With an official record of eight NWA, six WCW and two WWF world title wins, Ric Flair is without a doubt one of, if not the, greatest world champions in history. And if you include the five title reigns that aren't officially recognized, they further cements his credentials as "The Man."
